This invention relates to a method for drawing sub-micron ultraviolet luminous pattern on zinc oxide film. Wherein, dissolving the ZnA, sodium citrate and sodium citrate into deionized water, adjusting pH value in 10-11; dipping a clear substrate into the solution for supersonic oscillation at 60-90Deg to deposit ZnO film on the substrate; cleaning the film to remove reacted residue and dry in air lower than 400Deg; putting the film on SEM to irradiate with focusing electric beam on the film as request. This invention has high precision with low cost and long conservation time for wide application. |
